Find geolocation info of client through another API

This wiki shows how to get the geolocation info of the client using another server API It could be write also as extension but there are a lots of APIs that change the below code So, I wrote the below code that works for one of them (using

Add the file Geolocation.php in protected/components

class Geolocation {

    public static $ipaddress = null;
    public static $clientInfoLocation = null;

    public static function get_client_ip() {
        if (self::$ipaddress == null) {
            if (isset($_SERVER['HTTP_CLIENT_IP']))
                $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
            else if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
                $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
            else if (isset($_SERVER['HTTP_X_FORWARDED']))
                $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
            else if (isset($_SERVER['HTTP_FORWARDED_FOR']))
                $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
            else if (isset($_SERVER['HTTP_FORWARDED']))
                $ipaddress = $_SERVER['HTTP_FORWARDED'];
            else if (isset($_SERVER['REMOTE_ADDR']))
                $ipaddress = $_SERVER['REMOTE_ADDR'];
                $ipaddress = '';
        return self::$ipaddress;

    public static function getClientInfoLocation() {
        if (self::$clientInfoLocation == null)
            self::$clientInfoLocation = (unserialize(file_get_contents('' . self::get_client_ip())));
        return self::$clientInfoLocation;

    public static function getClientCountry() {
        $dt = self::getClientInfoLocation();
        return strtolower($dt['geoplugin_countryName']);

    public static function getClientLangCode() {
        $dt = self::getClientInfoLocation();
        return strtolower($dt['geoplugin_countryCode']);


Now, In any controller you chould use Geolocation::getClientCountry() or Geolocation::getClientLangCode()
